Atmospheric deposition of beryllium 7 in the Chesapeake Bay region [PDF]

open access: yes, 1989
Bulk (combined wet and dry) atmospheric deposition of the cosmogenic isotope 7Be was monitored at Solomons, Maryland, from March 1986 to November 1987.

Dry Deposition of Atmospheric Nanoparticles

open access: yes, 2021
The increasing number of pollutants emitted or released during and after the industrial revolutions caused major changes that were harmful to the environment and the health of the population. The harms resulting from air pollution were evident in the most industrialized regions, due to the large amount of pollutants emitted in these regions ...

Changes in dissolved iron deposition to the oceans driven by human activity: a 3-D global modelling study [PDF]

open access: yes, 2015
The global atmospheric iron (Fe) cycle is parameterized in the global 3-D chemical transport model TM4-ECPL to simulate the proton- and the organic ligand-promoted mineral-Fe dissolution as well as the aqueous-phase photochemical reactions between the ...

A simple model to estimate atmospheric concentrations of aerosol chemical species based on snow core chemistry at Summit, Greenland [PDF]

open access: yes, 1995
A simple model is presented to estimate atmospheric concentrations of chemical species that exist primarily as aerosols based on snow core/ice core chemistry at Summit, Greenland. The model considers the processes of snow, fog, and dry deposition.

Impact of mercury atmospheric deposition on soils and streams in a mountainous catchment (Vosges, France) polluted by chlor-alkali industrial activity: The important trapping role of the organic matter [PDF]

open access: yes, 2006
Total atmospheric Hg contamination in a French mountainous catchment upstream from a chlor-alkali industrial site was assessed using Hg concentrations in the deepest soil horizon, in the stream bottom sediments, in river waters and in bryophytes.

Nonequilibrium Atmospheric Plasma Deposition [PDF]

open access: yesJournal of Thermal Spray Technology, 2011
This study is a review of plasma enhanced chemical vapor deposition (PECVD) at atmospheric pressure. Sources for coatings over large area are presented. Millimetric torches and microplasmas are next studied for localized PECVD. A specific attention is paid to the way power is dissipated and the consequences it has on the deposition rate and on quality ...
